General Applications
Gears, shafts and other applications where a hard carborized case and a tough core are desired.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 7.86

Soft Annealing
Heat to 650-700^oC, cool slowly. This will produce a maximum Brinell hardness of 212.
